I wanted to provide a quick update on this thread.
First of all, thank you immensely, to everyone who provided guidance and offered their help. You all have proved that this is a top notch community and I really appreciate your assistance.
On to the topic. PCE Nuggets contacted me as he saw this thread on the forum and I began a dialogue with him about the issue, on how I had I troubleshot everything so far and if he had any suggestions etc on what I could do on my end to fix this, as I like to gain in knowledge and try to be self reliant.
PCE Nuggets offered to work on the system and resolve the issue for me, at no cost to me whatsoever, as he stands by his work. I shipped my Turbo Duo off to him and paid for the shipping myself, which I voluntarily did to place a high amount of insurance on it and signature required, as I am paranoid beyond measure about how the USPS handles my packages. Seriously...I've had packages arrive from the USPS that were marked FRAGILE in HUGE Letters everywhere on the package, and they still had massive, gaping craters the size of the box itself on the sides where it had been punctured. I don't take chances on anything I ship out to get repaired because of incidents like that.
And resolve it he did. I sent him my PCE Works discs that had failed along with my Turbo Duo and after some calibration and extensive testing on his end to ensure the problem was fixed, he sent the unit back to me.
Two of the PCE Works discs that gave me nothing but absolute fits when I tried to play them in the past, both booted up instantly without issue. Previously, the system wouldn't even get to a set disc error or anything. It would just endlessly spin. I'm going to play Spriggan and the other games I had issues with tomorrow after I get some sleep, but I am confident that the problem is resolved 100%.
I also sent in a PC Engine Shuttle as well, to be RGB modded while he was working on the Turbo Duo. That one I paid for.
Let's just say that I am beyond extremely happy with the end result of my PC Engine Shuttle's RGB Mod. The RGB Output from my OSSC into my HDTV is so sharp that it makes my eyes bleed. I loaded up Jackie Chan's action Kung Fu and all I saw was pure, unadulterated, crisp RGB BLISS.
So again, thank you everyone for your help. And to PCE Nuggets, dude, you rock. Again, I cannot thank you enough for helping me out as extensively as you have. It is so very awesome to know that reliable modders like you are out there who care extensively and deeply about the work they do.
Night all for now. Take care.
